ABSTRACT

The study focuses on the factors affecting the effective construction of diaphragm walls,retaining walls, management work related to the design, construction of reinforced concrete, the work of finishing diaphragm walls

In order to successfully implement the project, the investor, contractors and related parties must do a good job of assessing the causes affecting the quality of the diaphragm wall and earth retaining wall and do it early from the beginning of the project

Currently, the projects of office buildings and apartments for rent are all built with basements, the purpose is to increase the usable area on the same construction area due to the increasingly limited land area and the basement

to meet many jobs other usability The diaphragm wall construction method is one of the most commonly applied methods in high-rise buildings and basements The diaphragm wall has the function of waterproofing and stabilizing the structure of the building, but the construction of the diaphragm wall is quite complicated and contains many potential impacts that cause great consequences

The thesis presents the concepts, theories, management processes when constructing diaphragm walls, retaining walls, student use the tools and theories learned to present methods to evaluate the influence of factors together to serve as documents for the investor, project management board, supervision consultant, reference and take measures to prevent and avoid possible harms when implementing the project

In order to identify the factors that the effective construction of diaphragm walls,retaining walls in construction projects, a survey including 37 factors used to collect data from experience and certain knowledge people regarding the effective construction of diaphragm walls,retaining walls in construction There are 165 valid responses used in statistical analyses Multiple used include: mean method, Spearman rank correlation test, t test The test results show that the views of the three main groups involved in the project implementation process (the Investor, the Consultant and the

Construction Contractor) on the factors affecting the effective construction of diaphragm walls,retaining walls in construction projects have significant correlations with each other

SNA, it is possible to determine the level of impact between the factors

on the effective construction of the underground stage of high- rise buildings From the aforementioned results, project participants should pay close attention to the factors identified in this study to minimize the risk of the unexpected damages the quality of the underground stage of high- rise buildings
